This type of misanthropic thinking will get us nowhere and just make us look like total dickheads. Americans are fucking idiots, it's true. A lot of them have dumb, reactionary beliefs or just have totally incoherent beliefs that make them like a flag in the wind. But if we want change in the United States this is the population we have to work with. At this point though, We better be able to work with what we've got. It is increasingly clear we are on a short timeline to avoid catastrophic damage to our global society and the ecosystem that capitalism is destroying through its rapacious need for infinite growth.
There is cause to believe that the spell of the propaganda is breaking, and the illusions Americans have been living under aren't matching with the reality they live in. But the challenge is that have been intentionally deprived of the tools to think about their problems. The task of the left, in the short term, is to give them the language to talk about their problems then show the people that they don't have to live like this, that their lives could be easier now. This is a matter of survival, and that demands pragmatism.
There is no time for doomerism.
